StepKcal
StepKcal is a step-based calorie calculator that turns your real daily step count into a personalized Total Daily Energy Expenditure (TDEE), Basal Metabolic Rate (BMR), and calorie target for weight loss. It uses the Mifflin-St Jeor equation, a widely validated formula, combined with your actual step data to eliminate guesswork. Designed for anyone looking to lose weight or optimize their nutrition based on real activity levels, StepKcal provides a shareable report with a single one-time purchase — no subscription or signup needed.What Makes StepKcal Stand OutStep-based activity tracking: Instead of vague activity level descriptions (sedentary, active, etc.), StepKcal uses your actual daily step count from your phone or fitness tracker for precise calorie calculations.Science-backed formulas: Employs the Mifflin-St Jeor equation for BMR and a step-based NEAT (Non-Exercise Activity Thermogenesis) model to estimate calories burned from steps and daily activity.Personalized weight loss paces: Generates multiple calorie deficit options (e.g., 0.5 kg/week and 0.7 kg/week) based on your BMI and desired weight, with recommendations for safety and sustainability.Comprehensive report: Includes BMI assessment, calorie breakdown, macronutrient split (protein, carbs, fats), and weekly weight progress projections — all in one downloadable report.No subscription, no signup: A single $1.99 purchase gives you full access to your personalized plan, with no recurring fees or account creation.Who Should Use StepKcalIndividuals seeking science-based weight loss: Anyone tired of generic calorie recommendations and wanting a plan tailored to their actual daily movement will benefit from step-specific calculations.Fitness enthusiasts and casual walkers: Whether you track steps for general health or have a specific goal, StepKcal adapts to your current activity level and provides clear targets.Budget-conscious dieters: Those who prefer a one-time purchase over expensive meal plans or subscription apps can get a comprehensive calorie and macro breakdown without ongoing costs.Frequently Asked QuestionsWhat is StepKcal?StepKcal is a web-based tool that calculates your personalized daily calorie needs for weight loss based on your actual step count, age, gender, height, weight, and desired weight. It uses the Mifflin-St Jeor equation and a step-based activity model to estimate your TDEE and provide tailored calorie and macronutrient targets.How does StepKcal work?You input your age, gender, height, weight, desired weight, average daily steps, and walking pace. StepKcal calculates your BMR, adds calories burned from steps and non-step activity (NEAT), and subtracts a safe calorie deficit to produce multiple weight-loss pace options. Results include daily calorie goals, macronutrient splits, and a weekly weight projection chart.Is StepKcal accurate?StepKcal uses the clinically validated Mifflin-St Jeor equation for BMR and estimates activity energy expenditure based on step count and pace, which is a more objective method than self-reported activity levels. While individual metabolism varies, the tool provides a reliable starting point for calorie planning. For personalized medical advice, consult a healthcare professional.
spinyield
spinyield is a monetization platform for developers who use AI coding agents like Claude Code. It inserts a small sponsored line into the agent's status bar during waiting periods, turning idle time into passive income. The core problem it solves is that developers using AI agents spend significant time waiting for inference, and spinyield captures that attention without interrupting workflow.What Makes spinyield Stand OutUn-farmable impressions: Every ad impression is cryptographically linked to a real AI inference session, making fraud economically unviable.Flat 70% developer share: No tiers or hidden cuts — developers keep 70% of every ad dollar across impressions, clicks, and signups.Privacy-first design: The extension never reads code, prompts, or files; it only requests a line of text via a session nonce.Fail-silent architecture: If the API is unreachable the ad simply doesn't appear, ensuring zero disruption to the developer's editor or agent.Live bid market: Advertisers compete in real-time auctions for placement in the status bar, with transparent pricing and public leaderboard for opted-in campaigns.Who Should Use spinyieldAI agent power users: Developers who rely heavily on Claude Code or similar tools and want to offset API costs or earn passive income during long tasks.Open-source contributors: Those spending hours on agent-assisted coding can monetize their idle screen time without compromising workflow.Freelance and indie developers: Individuals looking for a secondary income stream that requires no extra effort beyond their normal coding routine.Frequently Asked QuestionsWhat is spinyield?spinyield is a browser extension and CLI tool that inserts a single sponsored link into the status bar of AI coding agents like Claude Code during thinking phases. Developers earn a share of ad revenue when the line is displayed, clicked, or leads to a signup.How does spinyield prevent ad fraud?spinyield uses Proof-of-Inference, an anti-fraud system that binds each impression to a cryptographically signed session created during a real, paid AI inference. The system checks for replay, frequency, plausibility, and collusion signals, making it economically unprofitable to fake impressions.Which agents and platforms does spinyield support?spinyield currently supports Claude Code in the terminal CLI and VS Code extension. Compatibility with Codex and Cursor is planned. The extension works on macOS, Linux, and Windows.
